A transfer conveyor which prevents collisions between works to be conveyed when the works to be conveyed or stored are carried on a conveyer track by a work support having a length shorter than the length of works to be conveyed, which permits reverse traveling during maintenance operations and the like. The collision preventing mechanism includes a sensing element which is biased into a contact position where it engages a leading work support on the conveyor track and is deflected, a sensing leverwhich mounts the sensing element and pivots in accordance with the contacting/deflecting operation of the sensing element, and a stopper lever downstream from the sensing element, which is connected to the sensing element to be displaced into the path of travel of the next trailing work support when the sensing element is in the contacting position, The stopper lever limits the travel of the trailing work support to a predetermined storage conveying interval.

Transfer conveyor

A hybrid carrying truck is disclosed which has merits of both of a skid carrier and a carrying truck such that it can successively and smoothly transfer between different carrying lines to carry a work whatever the carrying lines are and can secure a removing position from the carrying line to a refuge area freely and with safety. The hybrid carrying truck includes traveling wheels mounted at front and back positions on the left and right sides of a truck body for being rolled on a pair of rails to allow the truck body to travel along a carrying line, a pair of left and right skid members mounted on a bottom face of the truck body and elongated in a carrying direction of the hybrid carrying truck, and a truck hauling engaging member mounted at a central position of the bottom face of the truck body in a widthwise direction of the truck body.

A retainer dog is pivotally mounted on a pusher dog at the front end portion thereof and normally urged to a standing position. The distance between a retainer surface of the retainer dog and a thrust surface of the pusher dog is predetermined such that a space large enough for the retainer dog to rotate with a tilting radius can be obtained.

Pusher conveyor having pusher dog with retainer

The present invention provides a traverser, which includes a support member driven by a chain and movable between a carry-in rail and carry-out rail which are disposed parallel with each other. The support member transfers a truck from said carry-in rail to said carry-out rail. A groove for receiving a flange of a wheel of the truck is formed in an upper surface of the support member.

The present invention provides a pusher dog, which is mounted on a driving conveyor chain and normally urged to a standing position, and which is detachably hooked on a truck. The pusher dog tilt operation plate is mounted on a storage conveyor. An upward urging member pushes up the pusher dog tilt operation plate to abut a lower end portion of the pusher dog in such a direction that the pusher dog is made to tilt and is released from engagement with the truck. A press down member presses down the pusher dog tilt operation plate against the upward urging force.
